If your permanent tooth is accidentally knocked out due to trauma or sport injury, do not panic. Prompt and effective management of the avulsed tooth within the first 20 to 40 minutes can save the tooth.
Here are some simple measures that you can do:
If the tooth is dirty or contaminated, gently rinse the tooth under running tap water. Do not scrub or brush the root surface as it may have living peridontal fiber and cells. Hold the tooth crown while rinsing.
After cleaning the tooth and your mouth, try to re-plant (insert) the tooth into its socket again.
If it is not possible to re-plant the tooth back into its socket on the spot, place the tooth in milk, saline or water. Alternatively, you can bathe the tooth with your own saliva by placing it on the inner side of your cheek.
See a dentist immediately for emergency treatment.
